2.3.2.6.4 Setup Menu: Options – Autosave Spectra Periodically<br />
With this option complete spectra will be saved automatically in time. The following parameters<br />
can be set:<br />
• Time delay before first scan needs to be<br />
entered in seconds. After clicking the OK<br />
button, <strong>AvaSoft</strong> waits for this number of<br />
seconds, before the first scan is saved.<br />
• Time delay between scans needs to be<br />
entered in seconds. This defines the time<br />
between saving two subsequent spectra.<br />
If this number is set to zero, <strong>AvaSoft</strong> will<br />
save the spectra as fast as possible.<br />
• Number of scans to save: the number of<br />
spectra that needs to be saved can be<br />
entered.<br />
On top of the parameters that appear at the right, a checkbox shows: Save As Fast As Possible (no<br />
screen updates).<br />
If the white checkbox in front of this text line is marked, the Automatic Save option will always<br />
save the number of scans that have been entered as fast as possible.<br />
2.3.2.6.5 Setup Menu: Options – Automatic Save Dark by TTL Shutter<br />
If the laser can be closed by a TTL shutter, this software option can be used to control the shutter.<br />
The spectrometer will generate a TTL pulse on pin 13 of the High Density DB15 connector at the<br />
moment the dark data is saved by clicking the Save Dark button or File/Save/Dark menu option.<br />
This pulse can be used to activate the shutter.<br />
The next 3 integration time cycles after the Save Dark event, are used to get a stable dark<br />
spectrum. Then, this dark spectrum is saved and a dialog is shown to confirm. After clicking the OK<br />
button in this dialog, the laser is switched on automatically.<br />
To use this feature, the menu option ‘Save Automatic Dark by TTL shutter’ needs to be clicked in<br />
the menu setup-options. To disable this option, the menu option (which is marked as long as the<br />
‘Save Automatic Dark by TTL shutter’ is enabled), needs to be reselected.<br />
2.3.2.6.6 Setup Menu: Options – Suppress Save Comments<br />
This option, if preceded by a checkmark, disables the appearance of the comments dialog box if an<br />
experiment is saved as described in section 3.1.5.<br />
By default this option is OFF. After clicking the menu option it will be enabled (preceded by a<br />
checkmark).<br />
